To @ZZ whom it may concern: said extensions B" to confine the latter beoBe it known that I, CHARLES H. GOODNOW, tween the end walls C and saidend wall exa citizen of the United States, residing at Chitensions C',and thereby lock the side walls cago, in the State of Illinois, haveinvented of the box and their end extensions B" in 5 certain new anduseful Improvements in Paplace in vertical position. lVhen the end perBoxes, of which the following isadescripwall extensions C' are bentdownward inside 55 tion, reference being had to the accompanythe boxagainst the side-wall extensions B", ing drawings, forming a part ofthis specitithe supplemental extensions C" of the end cation. walls arepressed dat upon the bottoni of the Io Illy invention consists in animprovement box at right angles to the inside end walls or upon aweltknown form of paper box, and its extensions C', Fig. G, and serve toprevent 6o nature and novelty will be hereinafter dethe latter fromspringing upward and releasscribed, and particularly pointed out in theing the confined extensions B'l of the side claims. walls, this beingthe intended function and In the accompanying drawings, Figure lispurpose of said supplemental extensions C.

This form of blank is substantially My invention provideseflicient means for 85 old, and in folding it into box form thesidepositively locking the parts at both ends of wall extensions B' Bare first bent over inthe box in place and adds practically nothing wardupon the side walls B B and pasted to to the cost of the box or to thelabor of fold- 40 the latter, as in Fig. 2, to stiffen them and ing theblank into box form, and itconsists form double side walls for the box.The side in providing the supplemental extensions C" eo walls B B arethen bent up to vertical posiwith short locking extensions cat theiroppotion, their end extensions B" B" bent inward site ends, whichextensions c when the blank across the ends of the box, the end walls CCis folded into box form in the manner dethen bent upward to verticalposition against scribed catch under the lower edges of the the sideextensions B B", asin Fig. 3, and inner side walls B', as in Fig. 6, andposi- 95 the end-wall extensions C Cl then bent over tively lock theinner end walls or extensions the sidewall extensions B" B and downwardCin place against the confined side-wall exinside of the boxagainst theinner sides of tensions B. Fig. 3 shows the parts at ono end of the boxin position for one end-wall extension C to be bent downward inside thebox. As it is pressed downward inside the box the locking extensions c cbear against the inner surfaces of the side walls and are bent upward orbackward at right angles to the extensions C and C, as shown in Figs. 4and 4, and as the inner end wall or extension C is pressed on downwardand outward to vertical position against the end of the box thesupplemental extension C strikes the bottom of the box and is bent atright angles to the inner end wall or extension C and brought flatagainst the bottom of the box, and as it reaches this position thelocking extensions c c at its opposite ends are brought into Verticalposition and spring outward against the outer side walls B B of the box,immediately beneath the lower edges of the inner side walls B B, asshown in Figs. 5 and 6. The inner side walls B' of the box are made ofsomewhat less width than the outer side walls B, so that when foldedupon and pasted to the outer side walls there is a space left betweentheir lower edges and the bottom of the box, and the height of thelocking extensions c c is made to correspond to the width of this space,so that when the parts are pressed into the final position saidextensions will fit snuglyin the space between the bottom of the box andthe lower edges of the inner side walls B', as shown in Figs. 5 and 6,and by the engagement of their upper edges with the lower edges of theinner side walls B serve to positively and securely lock the parts inposition.

It will be understood that so far as the operation of my invention isconcerned it is not absolutely essential that the box be provided withinner side walls extending its full length, since only the portions ofthese side walls adjacent the ends of the box cooperate with the lockingextensions c, constituting the basis of my invention, and any othersuitable abutments upon the inner surfaces of the side walls of the boxwould coperate with the locking extensions c for the purpose described;but inasmuch as boxes of this character are usually provided with doubleside walls for the purpose of stiffening and strengthening the sides ofthe box and giving them a better finish, and inasmuch as in folding thebox the locking extensions c ride over the surfaces of i such inner sidewalls at some distance from the ends of the box, as in Figs. 4 and 4,and

the presence of the side walls therefore furnishes a smooth guideway forthe passage of said extensions and facilitates their engagement withtheabutments formed by the lower edges of the side walls at the extremeends of the box when the locking extensions reach their final position,it is a distinct advantage to employ such inner side walls in connectionwith my invention, as well as for the general purposes of a box of thischaracter.

Having thus fully described my invention, I claim- 1. In a folding boxof the character described, comprising a bottom A, side walls B havingthe end extensions B, end walls C having the extensions C adapted to bebent downward' into the ends of the box to confine the side extensionsB", and provided with the supplemental extensions C" adapted to restagainst the bottom of the box-the locking extensions c c projecting fromthe opposite ends of said supplemental extensions C" and adapted tocatch under suitable abutments provided upon the side walls of the boxand positively lock the parts in position; substantially as described.

2. In a folding paper box of the character described-that is to say,comprisingabottom A, outer side walls B provided with end extensions Band with the side extensions B folded inward against the side walls Band constituting inner side walls for the box, said extensions or innerside walls B being of less width than the outer side walls B so as toleave a space between their lower edges and the bottom of the box, theend walls C having the extensions C adapted to fold inward over the saidextensions B and downward inside the box to conne said extensions B",and provided with the supplemental extensions C" adapted to rest uponthe bottom of the box-the locking extensions c c projecting from theopposite ends of the supplemental extensions C" and adapted as theend-wall extensions C and C" arc pressed downward inside the end of thebox to ride over the inner side walls B and to catch under the loweredges thereof as the parts reach final position and positively lock theparts in such position; substantially as described.
